OK, we'll explain: Earlier this month, a Goldman Sachs employee penned a scathing Op-Ed that was published on his last day of the job. Greg Smith said that Goldman has a money-is-everything culture that is "toxic and destructive." He also wrote that they disparage clients, referring to them as "'muppets,' sometimes over internal e-mail."

So, Reuters reported earlier today that during a conference call with partners, this week, Chief Executive Lloyd Blankfein said "the company was taking Smith's claims seriously and was conducting a review of his assertions" partly by scanning archived company email for the term "muppet."
